closed contract. Whose terms constitute the entire agreement between the contracting parties and no clause or provision can be changed or modified without mutual consent. An insurance contract, for example, is a closed contract whereas a construction contract may not be one. See also open contract.
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. The volt is named in honour of the Italian physicist Alessandro Volta (1745â1827), who invented the voltaic pile, possibly the first chemical battery.
Volt (V). Volt is the electrical unit of voltage. One volt is the energy of 1 joule that is consumed when electric charge of 1 coulomb flows in the circuit.1V = 1J / 1C.olt (V). Volt is the electrical unit of voltage. One volt is the energy of 1 joule that is consumed when electric charge of 1 coulomb flows in the circuit.
